SWE library

SWE library is a network library written in javascript. This library provides easy interfaces to construct server-client web applications efficiently. Clients uses ajax call to be synced with the server. The server maintains three kinds of variables: sync-variable, server-variable, and signal-variable. The variables belonging to sync-variable are sent to the client periodically, while server-variables are not sent to the client. Signal-variables are only sent to the client once. The programmer just needs to classify the variables without concerns about how the variables are synced across the clients and the server.
